IMPROVEMENT lN'LAMP-FILLERS.

Specification forming part of Letters Patent No. 199,290, datedJanuary-15, 1878; application filed September 11, 1877. f

To all whom t 'may concern:

rALBERT T. HATCH, of South Elgimin the county of Kane `and State ofIllinois, have jointly invented a certain new, useful, and ImprovedLamp-Filler, of which the following is a specification, reference beinghad to the accompanying drawing, in which- Figure 1 is a top or planview of a lampfiller embodying our invention; Fig. 2, a vertical centralsection thereof; and Figs. 3 and 4 are like sections, indicating theconstruction of the induction-valve.

In the drawing, A represents an air-tight vessel, made, in the exampleshown, of tin or other suitable metal. It may, however, consist ofglass, and, in the latter case, it should be protected by an outershield made either of metal or wood, and it should, when made of' glass,be separated from the outer case or shield either by small webs orbraces, or by suitable packing material employed for that purpose.

B is a bail, hooked into ears on the vessel A to admit of the latterbeing carried with facility. C is a vertical tube entering the top ofthe vessel A and extending nearly to its bottom, as shown. D is a rotaryfaucet applied to the upper or'external end of the tube C. This faucetis constructed and operates like faucets of its class-that is to say,there is a lateral port in the side of the tube G, and this port lies inthe same plane with the tubular part of the faucet, so that the passagethrough the tube C and the faucet will be continuous when the port inthe tube is adjacent to or coincident with the tubular part of thefaucet. We so apply the faucet that this coincidence will occur when thefaucet is arranged in or nearly in a radial line, as represented in Fig.2 and by the broken lines in Fig. 1. The faucet, therefore, will beclosed by the act of turning the faucet into the position indicated bythe full lines in Fig. 1, and opened by turning it into the positionindicated by the broken lines. We deem it preferable to curve the freeend of the faucet, as shown, for the purpose hereinafter mentioned.-

E is an elastic bulb, having two ports therein, one serving as anair-induction port, and

the other as an eduction-port. Check-valves operate in connection witheach of these ports, so that by alternately pressing and releasing thebulb a current of air vwill be forced out intermittingly through theinduction-port.

The construction and operation of bulbs of this class are well-known,and we will there fore merely state that we employ such a bulb or otherair-injector for the purpose of there by forcing air into the upper partof the vessel A, as indicated in Fig. 2.

F is a removable cap covering the fillingport. We deem it preferable,for the purpose hereinafter mentioned, to provide the cap F with avent-valve, F', held to its seat by means of a spring, and so arrangedand applied that a downward pressure upon the valve or its stem willopen the valve.

G is a lid hinged tothe vessel A.

In order to use the apparatus now described for the purpose of fillinglamps, the bent end of the faucet D is inserted into or held over thefilling-orifice in the lamp, the faucet being first turned into theposition indicated by the broken lines in Fig. 1 and by the full linesin Fig. 2, thus opening the faucet, 'and allowing the lamp to be heldwith convenience while being filled. The bulb E is then manipulated inthe usual manner, and by this means air is forced into f the vessel Auntil a sufficient pressure is exerted upon the iuid to drive it outthrough the tube C and the faucet. This action can be thus continueduntil the lamp is filled. The outward now of the contents can be stoppedinstantly by depressing the valve F, when the fluid in the tube C willreturn to the level of that in the vessel, thus preventing any of thecontents from being spilled after the lamp is filled and before thefaucet can be closed. Without the valve F the elastic force of the airwould require great care to be used in preventing an outward flow ordrip after the lamp is filled and before the faucet is closed.

When the filler is not in use the bulb E may be bent down so that itsneck will be engaged by the faucet, as indicated in Fig. 1. The lid Grmay then be closed, and all the parts will be securely covered andprotected, besides being compactly arranged. The filler may be carriedconveniently by means of the bail.

An ordinary screw-cap may be employed instead of the valved cap F; andneither the bail nor the lid G are essential features of our invention,although We deem it preferable to employ them for the purposes setforth.

It will be perceived that the tube G, by extending nearly to the bottomofthe vessel, not only admits of all or nearly all the liquid contentsof the vessel being forced out through the tube, but the gas generatedin the upper part of the vessel is also prevented from escaping throughthe tube.

The necessity of making the vessels air-tight, in order that theprinciple of our invention may be applied, Will also tend to diminishthe number of accidents caused by explosions during the operation offilling lamps with kerosene and similar oils or iluids.

The apparatus is light, compact, and cheap, and may be convenientlyemployed for the purpose for which it is intended, as Well as foranalogous uses, such as iilling druggists bottles.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

l. Apneumatic lamp-ller consisting of the combination ofthe air-tightvessel A, having a lling-port; a ilexible air-injecting bulb, E,having., therein tWo valved air-ports or checkvalves, one serving as anair-induction and the other as an air-eduction 5 a discharge-tube, C,extending nearly to the bottom of the vessel, and terminating at itsupper end in the rotary nozzle or faucet D, having therein a portarranged to be opened and closed alternately during the rotation of thenozzle, substantially as and for the purposes set forth.

2. A pneumatic lamp-iiller consisting of the combination of theair-tight vessel A, cap F, vent F', leXible air-injecting bulb E, tubeC, and faucet D, all constructed, arranged, and operating together,substantially as and for the purposes specified.
